20 Claims. 1

This invention relates to recording devices and has particular relation to those instruments wherein a record of functions of machines and mechanisms are instantly and permanently recorded.

The primary object of the invention is the provision of an improved time recording instrument of varied adaptability.

Another object of this invention is the provision of a recording instrument which may be utilized for example to record the date, time and split second time of the operation of a circuit breaker and its return to operative condition.

Still another object of the invention is the provision of a recording instrument which may be utilized to record operations of related devices showing the relation between similar or dissimilar operations in such a manner that the com parative times of operation and their relation will be apparent from an inspection of the record.

Still another object of the invention is the provision of a recording instrument which may be utilized to record the operations of a machine, mechanism or device and which is provided with a timeestamp for recording the starting and stop ping times during long intervals and an additional recording device for concurrently recording short intervals of time, thus making it unnecessary to run a record sheet continuously for a long interval oi operation, or nen-operation, of the machine, mechanism or device, a record of whose operation is being recorded.

Referring to the drawing wherein is illustrated one embodiment of the invention:

Fig. l is a diagrammatic illustration showing a lay-out and one circuit for the operation of the invention.

Fig. 2, 3, and 4 are illustrations of the record sheet showing diiierent sets of recordings.

Throughout the drawing and speclcation, the same reference characters refer to the same or similar parts.

In the particular modification illustrated and described in Fig. l, `a layeout is shown for recording the operation of a series of circuit breakers, only one complete circuit being included. The addition of other circuits will be fully understood by those skilled in the art after a reading of the speciiication in connection with the drawing.

In the drawing, the numeral 20 designates the 2 switch which is indicated in dotted lines to show its connection from the switch point 26o to either one of the Contact points 2Gb or idc. It is to be understood that the operation of the switch 20 connects the point 20a with the point 2de when the circuit breaker is closed and connects the point 28a with the point Zilla when the circuit breaker is open. It is to be further understood that the circuit breaker operates the switch 20 and except for the instant when a change is taking place, the switch 20 connects the Contact point 28a with either the contact point 23h or the contact point 20c, but never connects 2da with both contacts Zb and 20c at the same time.

Across the points 28a, 2Gb there is connected a red signal lamp 23, and across the points Eea, 243e is connected a green signal lamp These lamps 23, 24 are located at a place on the switch board where they may be plainly seen. The contact point 20a is connected through the lamp Z3 and the point 2 Ilb to the negative side 2l oi," a source of direct current, by means of the `conductor 21a and the point Eilat is connected through the lamp A2li and the contact point 20c to thev positive side 22 of the same source of direct current by the conductor 22a. The point 2da, also connected continuously with the positivel side 22 Of the direct current supply by means of the conductor 22h, through the coil 25a 0f the relay 2,5. The relay 25 illustrated at the right side o f Fig. l includes a coil 25a, having an armature 25h, which is normally held away from the core of the coil 25a by the spring 25e. A non-.conducting operating rod or connection 25d is in position to be operated by the armature 251). The operating rod or connection 25d is supported by three resilient contacting members which are designated respectively, 25e 25h and 2,51. The contact member 25e normally contacts the coacting contact member 253 when the coil 25d is not energized and when the coil 25a is energized, the 4contact between the contact mein,- bers 25e and 251 is broken and contact is at once made by the contact mem-ber Eile with the ccntact member 25g.

The contact member 25h is normally in contact with the contact member 257 when the coil 25a is not, energized, but when the latter is energized, Contact with the contact member 25yl is broken 3 and contact is at once made between the contact member 25h and the contact member 25k.

The resilient contact member 251 is normally out of contact with anyl coacting contact member when the coil 25a is not energized, but when the latter is energized, contact is at once made with the contact member 25m.

The results of the operation of the armature 25h by making and breaking of contact between the above-described contact members will be later described, It is to be understood that there is one relay unit 25 for each switch 20 and each circuit breaker or other unit, the operations of which are to be recorded. l

The connections for-the contacting members of the relay 25 will now be set forth. The contact member 25j is connected to a coil 28a of the relay 28, the other end of the coil 28a being connected through a condenser 21 to the contact member 25g and the contact member 25j. It is to be noted that the contact member 25J is connected to the contact member 25k and the contact member 25g is connected to the contact member 257.` The capacity of the condenser 21 would depend upon the characteristics of the relay coil 28a. It is thus clear that the result of the operation of the bar 25d is the reversal of the potential at the terminals of the condenser 21 and the impulse energization of the coil 28a.

The contact member 25e is connected through the conductor 22o to the positive (-1-) side 22 of the direct current line. The contact member 25h is connected through the conductor 2lb to the negative side 2l of the direct current line. The contact member 251 is connected to the stylus 3|! by means of the conductor 29 and its coacting contact member 25m is connected through the 12,000 ohm resistor 3h and the conductor 32h to the stylus power bus bar 32.

In the construction illustrated, the contact members 25e, 2511, and 251 are of resilient material which normally holds them, respectively, in contact with the contact members 253, 257 and out of contact with contact members 25g, 251e, and 25m, until the coil 25a is energized.

The relay 23 has two electro-magnetic coils 28a, 2817, and an armature 28o which is moved in opposite directions by the respective coils 28a and 28h. A spring retainer 28d is in position to hold the armature 28e in either one of its limits of position until such time as one of the coils moves it to its other position, in a well-known manner. A non-conducting member operating rod 28e is provided in position to be operated by the armature 28e when the coil 23a isenergized. Connected to the operating rod 28e are three resilient contact members 281, 28h. and 28k. These contact members 2812 2811, and 28k are in position to contact, but are normally out of contact with the contact members 28g, 287' and 281. When the armature 28e is operated by the coil 28a, the above mentioned contact members 28]', 28h and 28k close contact with their respective contact members, the armature 28o being held in this position by the retainer 28d. When the coil 2819 is energized, the retaining action of the retainer 28d is overcome and the resilience of the spring contact members 28j, 28h and 28k will return them to the positions shown in Fig. l.

The conductors from the contact members of the relay 23 will now be described. The contact member 28j is connected through the conductor 32e to the stylus bus bar 32. Its coacting contact member 28g is connected throughthe conductor 31a to the 220 volt alternating current ungrounded conductor 3 l. From this it appears that, since contacts 25m and 251 have already been closed, a circuit has been established from the ungrounded 220 volt A. C. bus bar 3|, through conductor 31a, contacts 28g, 28j, conductor 32e, stylus bus bar 32, conductor 32h, resistor 3 Ir, contacts 25m and 251, conductor 29, stylus 30, record sheet 50, ground plate 52, to the grounded side of the 220 volt A. C. power.

The resilient contact member 28h, is connected through the conductor 2Ic to the negative side 2l of the direct current line. The contact member 281 is also connected through the conductor '.llc to the same line conductor 2l. The contact member 23j is connected through the conductor 33a to the time stamp bus bar 33. The resilient contact member 28k is connected through the relay coil 281) and the conductor 34a to the cycle release bus bar 34.

The connections to the relay 35 and its construction will now be described. This relay 35 has two operating coils 35a and 35h. The armature 35c is operated alternately and in opposite directions by the respective coils 35a and 351) and is provided with a resilient retaining member 35d which holds the armature 35o in the position to which it has been moved until the other coil is energized in a manner already described for its counterpart 28d.

The relay 35 is provided with two contact members 35e and 35j, the armature 35e itself also acting as a conductor. The coil 35a is connected at one end through the conductor 34h to the cycle release bus bar 34. Its other end is connected to the contact member 35e. The coil 3511 has one end connected through the conductor 33h to the time stamp bus bar 33. Its other end is connected through the conductor 35 to the contacting member 31a for normal contact with the pivoted contact member 31. The armature 35e is connected through a condenser 35g and a conductor 35h to the contact member 35j.

Contact member 35 f is connected to time stamp relay coil 38a and relay armature 38e by a conductor 38h. Condenser 35g is connected on one side to relay armature 35e and on the other side to the conductor 38b, thereby producing a set of connections in which the condenser 35g is shortcircuited through the conductor 35h when the arm 35e is in its position of contact with the contact element 351. Condenser 38d is connected with armature 38o to contact member 38e. Relay armature 38e is normally held in contact with contact 38e by a spring 38X, when relay coil 38a is deenergized.

The condenser 38d and the condenser 35g are provided merely for spark suppression.

One conductor 39a from the platen solenoid coil 39h of the time stamp, is connected to the Contact member 38e. The other ends of the respective coils 38a and 39D are connected together by the conductor 38j and 39e and the joined ends are connected by the conductor 22d to the positive side of the direct current line. The solenoid coil 39h operates a platen 35d in a position immediately below the record sheet ll and opposite the line of styli, 3G, 36a, 3th, 38e, 33d, 30e and 30] provided for the respective units, the operations of which are being recorded.

Above the sheet 4U and in a position above the platen 39d is a time recording stamp clock 391. The printing ribbon 39g is located between the type of the clock 39j and the record sheet 4D, so lthat when the solenoid coil 39h operates the platen 39d against the record sheet 46, the printing ribbon 39g will print the time on the record sheet 4B, in accordance with the setting of the clock type at the instant of operation of the platen 39d.

The construction of the means for operation of the record sheet Il will now be described.

In position to be operated when the platen 39d is moved by the solenoid coil 39h, is a spring contact member 3%. Coacting with the contact member' 3th and normally out o contact therewith, is a contact member 38j. The contact member is connected by the conductor 2id to the negative side 2i of the direct current line. The contact member 39j is connected by the conductor llc to a relay coil fila of the relay 4l. The other end of the coil Illa is connected through the conductor 22e to the positive (et) side 22 of the direct current line.

The coil Illa and a second similar coil 4th operate in alternate opposite directions on the armatiue 42o. This armature tic has a spring retainer 4|d, similar in construction and operation to the retainers and d already described. The armature is connected through the conductor 22] to the positive (-1-) side of the direct current line.

One end of the coil Mb is connected to a contact member j and its other end is connected to a contact member 62a in position to contact the pivoted contact member when the latter swings upwardly as will be later described. This swinging contact member l2 is connected through the conductor 2 lf to the nega-- tive Side 2| of the direct current line. A suitable shaft 43 is suitably journaled and carries a disk i4 having a lifting lug on its periphery. This lifting lug fida is in position to raise and lower the pivoted contact member 42 as the lug 44o comes in contact therewith. This latter action closes and opens contacts between the contact member '12a and the coacting contact member 42. It should be lnoted that the lug 44d is located so that the contact members 42 and @2d are closed and opened when shaft 43 has made about one half ci its revolution.

The shaft carries a sprocket which is connected by a chain to a sprech-et Ille' on a shaft 48 through a friction device so that the record sheet be moved by hand to register with the Styli. Mounted on a shaft i8 is a roller 43d. This shaft also carries a. pulley 4811 which operates a drive belt 80 to a similar but preferably a slightly smaller pulley 48d. This pulley 48d is mounted on a shaft 43e upon which is a take-up roller 48j for receiving the used end of the record sheet 4.

On the shaft 43 is mounted a one-revolution clutch 45 having a stop lug 45d. This lug 4to is in position to be engaged by a swinging stoparm 46. Integral with the continuously operating member of the one-revolution clutch d5 is a gear 45h which is ccactively engaged by a gear 41 driven continuously by a power motor 4e.

A lsO mounted on the shaft i3 is :i disk 5B having a lug @idc in position to lift and lower the swinging contact member 3l already described. The contact members 3l and 31a are normally in contact but as the shaft 43 revolves and a lug 50a lifts one end of the swinging contact member 3l, the contact Sla is broken and the contact member 3l is moved into contact with the contact member S'lb.

The lug 5ba is so positioned on its disk 5t that contact between the contact members El and 31a broken and immediately contact is made and again broken between the Contact members 3l and 31h, followed immediately by the restoration of contact between the contact members 31 and 31a-all immediately prior to the stopping of the turniloer of the shaft 43 by the operating of the one-revolution clutch 45. The contact member is connected through the conductor 34o to the cycle release bus bar 34. As the lifting lug Elia passes and permits the swinging contact member 31 to lower, the contact be tween the latter and the contact member kSlb is broken. It is to be noted that the swinging contact member 37 is connected through the conductor 22g to the positive side 22 of the direct current line.

Connected to the swinging stop member 45 is a rod 51a which is operated by the solenoid coil 5| to disengage the upper end of the swinging stop member i6 from the lug 45a of the onerevolution clutch 45. The rod 5ta is returned to position shown in Fig, 1 when solenoid coil tl is deenergized by a spring 54o.

The solenoid coil 5l has one connected to the contact member lig of the relay li by the wire Sib and the other end through the cone ductor 2 le to the negative side of the direct current line.

It is to be noted that the Styli above the record sheet 40 are provided with a coacting grounded bar or plate 52 below the record sheet.

The several component parts of the structures and circuits diagramatically set forth in Fig. 1 having been described, the operation of the whole will now be set forth.

Assuming the parts and circuits to be as illustrated in Fig. l, with the parts in normal operation with the circuit breaker closed and connected to the present invention and ready to coact therewith, the lamp 23 will be lighted and the lamp 24. will be shunted out. As the circuit breaker opens, the switch 23 will break contact between contact members 20c and 20c and establish contact between the contact members 20a and 20h. The lamp '2.4 will light and the lamp 23 will be extinguished. This action places the relay coil 25a across the direct current circuit and the armature 25h is drawn to the right. This armature action moves the rod 25d to the right. At once, the connection between the stylus power bus bar is established through the bus bar 32, the conductor 322), the resistor 3Ir, the contact member 25m, 251, and through the conductor 2e to the stylus 30. The grounded plate 52 for coaction with the stylus has already been described.

The movement of the armature 25h and its coacting rod 25d opens a circuit, at the contacts 25e and 25j from the positive line 22 to the condenser 27, which is normally charged by the D. C. supply voltage, thus maintaining the relay coil 28a de-energized. |The movement of the armature 25h and its co-acting rod 25d, also connects a second charging circuit to the condenser 2l' at which time the relay coil 28a is momentarily energized and the armature 28c is drawn to the coil 28a.

It should be noted that when the condenser 21 is fully charged, the entire voltage of the direct current line appears across the condenser terminals, but no current ows through the condenser. Under these conditions, the relay coil 28a is de-energized but in condition to act on reversal of the potential at the condenser terminais. When, on energization of the relay coil 25a and movement of the armature 25h, the poerosie tential at the terminals of the condenser-2l is reversed, the relay coil 28a will be energized and the armature 28o will be drawn toward the coil 28a. The retaining member 28d holds the armature in this position until coil 28h draws'it to its normal position as will later appear. Summarizing, the function of the relay is to (1) place the stylus bus bar in connection with the stylus corresponding to the circuit breaker which has just operated and (2) to operate the coil 28a, of the relay 28 for the purposes which will presently be made plain. f

Returning to the relay 23 and the movement ofthe armature 28e to the left, the bar or rod 28e moves also to the left and is locked in position as already pointed out, by arm 28e through the action of the retaining member 28d. This action closes the circuit from the stylus power bus bar 32, through the conductor 32e, the contact members 28j, 28g and the conductor 3io to the 220 volt alternating current bus bar 3 i. Since as already pointed out, the stylus 30 has been connected to the stylus power bus bar 32, the connection of the bus bar 32 to the alternating current bus bar 3|, places the 220 volt alternating current on the stylus 30, and since the alternating current line 3l is grounded, through the secondary coil of the transformer, as shown, as is also the plate 52 beneath the stylus 3Q, it follows that the current will pass through the conducting teledeltos chart between the stylus 30 and the grounded plate 52 as long as these two coactling circuits are connected. The chart or record sheet 4U which is between the stylus 3i) and the grounded plate 52 will receive the current which will pass each time the current reverses its direction-with the cycle current it being 120 times per second. The record sheet itself is of a type which will indicate by a small dot, each time the current passes. This type of record sheet is Well known in the arts and for this reason Will not be further described. As the record sheet moves while the stylus carries the 220 volts, alternating current, as will later be described, it follows that by counting the number of dots made on the record sheet, or observing the lengthof the dotted line, the time the circuit breaker is out will be indicated, provided the record sheet moves continuously during the whole time.

'I'he operation of the relay 2t by its coil 28o,

lproduces further action. The action of the movement of the bar 28e to the left, bringing the contact members 23h and 227' together, completes a circuit as follows: From the negative side 2l of the direct current line 2 l, through the conductor 2 lc, the contact members 2 8h, 231', through the conductor 33a, the time stamp bus bar 33, the conductor 33h, the coil 35h of the relay 35, the conductor 36, the contact members Sie, 3l, the conductor 22g to the positive (-1') side 22 of the direct current line, thus completing the circuit.

The energization of the coil 3511- moves the armature 35o to the right where it is retained bythe retainer 35d until the coil 35a is energized to move it in the opposite direction. This movement of the armature 35o to the right completes the following circuit: from the negative side 2| of the direct current line by the conductor 2| g through the armature 35e, the contact member 35j, the conductor 35h, the conductor 38h; the armature 38o, the contact member v38e, the conductor 39a, the time stamp coil 39h, the conductor 39e to the positive (-1-) side 22 of the direct current line. This operates theltime stamp S platen 39d to record the time on the' upper surface of the record sheet 40, the details of which have already been described. A branch circuit from the conductor 38h through the delayed action time stamp relay coil 38a, the conductors 38f and 22d to the positive side (-1) 22 energizes the delayed action coil 38a to break the circuitjust described, at 39e, in order to return the platen 39d from its stamping position. The complete stroke and return of the platen is extremely fast. However this return of the platen does not return the armature 35e which is retained in its right hand position to the retainer member 35d. The movement of the armature 35e to theright also made a preparatory setting of the later cycle release by connecting the negative side 2l of the direct current line through the conductor 2lg, the armature 35o, the contact member 35e, the relay1 coil 35a and the conductor 3427 to the cycle release bus bar 34, which latter at this time is not energized'. It will be noted that the coil 38a will be kept energized until such time as the armature 35e is moved to the left by energization of magnet 35a which moves the armature 35o, thus breaking the circuit to the coil 38a at the contact 35i. When the coil 38a is deenergized, the spring 38X pulls the armature 38o into contact with the contact member 38e;

It will be recalled that the coil lla is connected by the conductor 22e to the positive side 2210i the direct current line and that a normally open circuit is connected to the other side of the coil lila through the conductor All e, the vopen contact member 399, the spring contact member 39h (held out of contact by the platen 39d), through the conductor 2id to negative side 2l of the direct current line.

As the platen 39d is raised, the spring contact member 33h contacts the contact member 391' and immediately thereafter separates, with the result that momentary energization of the coil Ala takes place. This causes movement of the armature llc to the right Where it is held by spring retainer Md, causing the armature Mc, which is connected to the positive (-1-) side 22 of the direct current line, to contact with the contact members lllf and Mg. The contact of the armature lilo with the contact member M, establishes a preparatory, and open, circuit as follows: from the negative side 2l of the direct current line, through the conductor Zlf, the swinging contact member 42, the normally open contact member 42a, the conductor 42h, the coil Mb, the contactA member M, the armature Mc, and the conductor 22j to the positive side 22 of the direct current line. As this circuit is open at the contact member :42st, the coil lib is at this time not energized. However the closing of the Contact dlg with the armature llc completed the connection to the solenoid 5l as follows: from the negative side 2l of the direct current line, through the conductor Zie, the solenoid 5l, the conductor 5Ib, the contact member lig the armature ele and the conductor 22j to the positive (1-) side '22 of the direct current line.

Energization of the solenoid 5l exerts a pull on its rod lila which causes a withdrawal of the upper end of the swinging stop member 4t with the resultant release of the lug 45a of the-onerevolution clutch :i5 permitting it to engage. But since the gear fl? is continuously driven by the motor i9 and in turn continuously drives'the gear 45h of the one-revolution clutch d5, it fol'- lows that the shaft 43 will be at once putin carried around for one full revolutionuntil they stop lug lia engages the top of the swinging stop member llt, when the one-revolution clutch will be disengaged and the movement of the shaft 43 stopped. When shaft d3 has made about onehalf revolution the lifting lug lll-'ia lifts the swinging member 32, a momentary circuit is completed as follows: from thenegative side 2i of the direct current line, through the conductor 2H, the swinging contact member t2,l the contact member 42a, the conductor fi2b, the coil dll), the contact member dif, the armature Mc and the conductor EL to the positive (-l-l side oi the direct current line. This energize-tion of -the coil Mb moves the armature lic to the left, thus breaking the connection between the armature 4to and the contact member Mg. Since the energization of the solenoid 5i s thus destroyed, the latter will permit the swinging stop member #l5 to return to its normal position to intercept the stop-lug 45a on the completion of its one revolution-to thus stop the shaft 43 from re volving. In addition, the movement of the armature Hc to the left, breaks connection between the armature Mc and the contact member lilf, thus cle-energizing the relay coil Mb which caused the-movement. The retaining member Hd operates to hold the armature llic in this left position until again operated by the coil Ilia. Also continued revolution of shaft 43 moves the lifting lug Het past the swinging member 42, breaking the connection at contact members 42 and 42a.

lAnother result of the rotation of the shaft 43 is that just before the revolution is completed, the lifting lug 5ta raises the swinging contact member 3l, breaking its contact with the contact member Sla and closing the contact with the contact member S'b for a short interval after which contact with S'b is broken and contact between 3l and. Sla again made just as shaft 4S stops rotating. The breaking of the contact between the swinging contact member 3'! and the contact member 37a, de-energi'zes the coil 35h to which the latter is connected by the conductor 36.- While the coil Itb is so de-energize'd, contact is made between the swinging contact member 3l' and the contact member fl'b, which com" pletes the circuit irom the cycle release bus bar as follows: 'from the cycle vrelease bus bar Sill through the conductor 34o, the contact member 37b, the swinging contact 3l, the conductor 22g to the positive side 22 of the direct curu rent une.

t has already been pointed out that two other connections from the negative side 2! of the direct current line to the cycle release bus bar, have been made as preliminary settings. These (l), by way oi the conductor 34a, the coil Reb, the spring contact member 23k, the contact member 28? and the conductor Zic to tlienegs. .ve side 2l of the direct current lineg' and (2), from the negative side 2l of the direct current line by the conductor 25g, the armature 35e, the contact point 35e, the coil 35a, nd tane conductor 3th to the' cycle release bus From the foregoing, it is clear that with the connection between the swinging contact member 31 and the contact member 3113, a connection is established for coils 28h and 35a across the direct current line.

This connection causes the energize-tion of the coils 23h and 35a, and, as relay coils 28u. and 35h are fle-energized, a resultant return of the respective armatures 28o and 35o to their normal positions takes place as illustrated in Fig. l. In the case of the relay 23, this action breaks all contacts previously made and leaves the parts as shown in Fig. l.

From the above it is clear that the operation has been such that the relays 28, 35, 38, and lll have been returned to their normal positions after operation. The relay has not yet been returned to its normal position and the stylus 3i) is still connected to the stylus bus bar 32 through conductor 29, contact members 251, 25m.

' resistor 3h andconductor 32h, but is not making any marks as the connection between the 220 volt ungrounded bus bar 3l and the stylus (it bus has been broken at contacts 28o' and 28j. This status will continue to be until such time as the circuit breaker or another circuit breaker is again closed and the switch 2@ disconnects conT tact members 23a and 20h and connects contact members ila and 20c. When this takes place, the lamp 23 is lighted and the lamp 24 is shunted out.

In addition, since both terminals of relay coil 25a are connected to positive bus 22 by conductor 22h and 20a, 2&0 and conductor 22a, it is deenergized and the spring 25o moves the armature 25D to its normal position, illustrated in Fig. l.

As the rod or bar 25d reaches its left hand position, the connections between the spring i contact 25e and the Contact member 25g and between the spring contact 25h and the contact member 25k are broken and contacts made between the spring contact member 25e and the contact member 251 and between the spring contact member 25h and the contact member 259'. This reversal of potential causes a charging current through the condenser 2'! and the relay coil 28o and causes its operation to again move the armature 28o to the left. In this operation, however, only two of the three pairs of contacts are effective to produce any results-the connections between members 23h and 287' which connection is made for operation of the time stamp and between contacts 28k and 281 for connection to the relay 28h for the cycle release. While connections will be made between contact members 28j and 28g, these connections for the stylus power bus bar will not be ei'ective because at this time, the armature 25d is at its left hand position as shown in Fig. 1 with no contact between the contact members 251 and 25m, and since contact between these contact members is necessary for the conduct of altelw nating current to the stylus 30, no action results from contact between the contact members 281 and 28g.

The operation of the rod or bar 23e to the left to close the contact betwecn the contact members 28h and 287', causes the operation of the time stamp already described, except at this time, the stamp indicates the closing of the circuit breaker or the return to normal of any other machine, mechanism or device, the functions of which are being recorded.

Except for the non-'operation of the stylus to 11 make dots on the record sheet, the other parts pass through a complete cycle in the same manner as previously7 described.

In inspecting the record sheet, the time stamp records are readily identified since the record starting time stamp will be at the beginning of the dot recordings While the closing time stamp will be at thel end of such record, unless the breaker closes before the chart stops moving, in which case there will be no time stamp record for the closing as later described.

As there is one relay 25 and one relay 28 for each stylus and for each switch 20 and one switch 2e for each circuit breaker or other machine, mechanism or device, the operations of which are being recorded, it follows that the ren lay 28 and the relay 25 corresponding to one switch 29 may have their armatures in position corresponding to their switch 20 position while those of relays 28 and 25 corresponding to another switch 28 for another machine, mechanism or device may be in independent positions which correspond to the position of their switch 20.

From the foregoing description it may be seen that the energizingr of any relay 25 causes its corresponding stylus to be connected to the stylus power bus 32A until such time as it is again deenergized.

The energizing or cle-energizing of any relay 25 also causes operation of relay 28, feeding of a definite length of record sheet through the recorder, connection of the stylus power bus to the 220 volt power source and with one exception, the Stamping of the time. Hence each time the paper moves all styli connected to an energized relay 25 will mark a dotted line. Thus each time a relay 25 operates, the time is recorded and a dotted line on the record sheet shows the position of every relay 25 connected to the recorder.

As has already been noted, under one condition the operation of a relay 25 does not cause operation of the time stamp. After operation of one relay 25 has started the revolution of the shaft 43, the time stamp cannot again operate until the cycle is completed. This is because the relay 38 is energized breaking the circuit to the platen solenoid 39h at contact 38e. This prevents the platen from striking the record chart While it is in motion and also prevents repetitive stamping of the time before the time stamp type have had an opportunity to indicate a change of time. In such a case the paper will always have moved some distance from the point where the time is stamped before the second stylus (say 30a) starts its line of dots.

It should also be noted that should the relay coil 25a be energized, reversing the position or" armature 25h at any time the shaft 43 is revolving, the relay coil 28h will momentarily be energized. As the armature 28o is already in the energized position, the only eiect of such an operation is to start or stop the line of dots being made by kstylus 30, before the record sheet reaches the end of its cycle.

There is but one each of the record sheet 4U, drive means therefor and the relays 35, 38, ll and their connections.

The conductors from other switches 20, relays 25 and other styli as 30a, 30h, 30C, 30d, Sile, and 3W will all be connected to the same bus bars and to their respective terminals, contacts, conductors and condensers 21 in the manner already described and as fully understood by those skilled in the arts.

It is to be understood that all of the connections and .apparatus to the left of the conductors 22d, 39e and 36, and including them, are for common use of the circuitsV for the Several circuit breakers or other devices which may be used with this recording apparatus and consequently there is one set only of these connections and apparatus for the whole recorder.

It is to be understood also that all of the connections and apparatus to the right of and including the conductors 2lb and 32e, are indi.- vidual to the circuit breaker or other device with which this recorder is used. Consequently all of these connections and apparatus must be repeated for each circuit breaker or other device with which the recorder is used.

The connections to the ungrounded 220 v. A. C. line 3i, the stylus power bus bar 32, the time stamp` bus bar 33, the cycle release bus bar 3'4 and the 125 v. D. C. service lines 2l and 22 are made as shown.

In the foregoing description, the construction and operation of the mechanism for recording the operation of one mechanism, machine or device, as a circuit breaker, has been described. From the construction, it will be clear that even though the switch 2i! corresponding to the stylus 30 is operated to causev the stylus 3U to make a record, a similar stylus as 30a may be caused to start recording by operation of a second switch 2i] corresponding to and operated by a second machine, mechanism or deviceas a circuit breaker. By comparing the dotted lines on the record sheet with the time stamp recordings lit may be determined which breaker opened first and the relation between the two openings may be studied.

Assume a situation where the first switch 25 has been operated by its circuit breaker, and the circuit breaker remains in an out position long er than the time it takes for the shaft 43 to rotate. In this case, it is clear that while the iirst operated relay 25 may remain in an operated position-with the armature 25o in its right hand position, the alternating current will be disconnected from the stylus 35 at the end of the cycle which comes with the energization of the cycle release bus bar. This will, oi course stop the stylus recording. Further, the movement of the record sheet is stopped.

This stopping of the recording after a predetermined time of operation of the one-revolution clutch 45 is brought about by several steps, one of which is the operation of the relay coil 28h to move the armature 28e to its normal inoperative position, as shown in Fig. l. The stopping takes place when the cycle release bus bar shall have been energized by closing the cycle release circuit by the upward movement of the swinging contact member 3l to close contact with the contact member 37a. This takes place near the end of the revolution permitted by the one-revolution clutch 45. In this connection, it will be remembered that the relay coil 28a moves the armature to the left by the charging current through the 6 mfd. condenser 21 which movement closes the contact members 28k, 281 connecting the coil 28h to the cycle release bus bar 34 to prepare for reset operation when the contact is made between the swinging contact member 31 and the contact member 31a.

In case a second circuit breaker then opens causing closing of its switch 20 across the contact points 20a, 20c, its stylus as 30a, will at once take the 220 volts of alternating current from the un- 13 grounded bus 3 l, through contact of its 28 relay to the stylus power bus and contacts of its relay 25.

As a second result, the stylus 30 will again be energized since the relay Isoil correspondn ing to the first switch 2G is still connecting the stylus 36 to the now energized stylus power bus 32. And as the stylus Sila becomes connected to the stylus power bus Sil by the contact members of the relay coil 28a of the second circuit breaker, it follows that both the stylus 3@ and the stylus 30a will begin at the same time to record and will continue until either (l) the relay coil 25a of any particular circuit is de-energized by operation of its switch 2t or (2) the shaft A't3 makes its complete revolution and stops the recording of all styli by operation of the swinging contact member 31.

In the same way, if the preparatory settings of the closing ci contact member 251 with contact member 25m have been maintained by the continued energization of both relay coils 25a and anothcr-third-relay coil 25a is energized by a third switch 2E, its stylus as 30h and all oi the others corresponding to other machines. mechanisms or devices-as the circuit breakers, whose relay coils 25a are energized, will again start recording until stopped in ione of two ways just set forth. l

"Ihus, when one or more breakers may have been opened and not yet closed, the operation of an additional switch 2@ by the opening of its breaker, will cause the styli of the previously opened breakers to again come into operation for the period of the cycle initiated by the latest opened breaker. And because of this, it is possible, as above pointed out, to determine from a study of the record sheet, how many and which circuit breakers were open at the same time and at any given time and also the relation between their times of opening.

And this is true even though the time of being open may be only a split secondin which case the dots may be counted or the length of dotted lines measured to obtain the exact times.

It is to be noted that since the starting of a cycle by the switch 220, will cause the shaft i3 to make a full revolution, the same switch 253 may open and close two or more times during the second or other pre determined time which it takes the shaft d3 to revolve. In such a case, the spacing of the dots of the line--indicated by the time when the breaker may have been closedand the number of dots made will give full in formation on the time the breaker will be out, it being remembered. that the beginning of each cycle, whether it correspond to a circuit breaker opening or closing is marked with a time stamp record, but that after a cycle has been started no vfurther time stamp record will appear until that cycle is completed and another started.

It is also evident that since the starting of a cycle by the switch will cause the shaft 43 to make a full revolution, a second switch 2d may also open or close one or more times before shait 43 ceases revolving. The result of this is that stylus Sila corresponding to the second switch 2li will make an interrupted line of dots, similar to that just described for stylus 30.

In the foregoing description, there have been described several different types of operation: where one circuit breaker opens and within a second oic time, a second circuit breaker opens. the first one still causing a record to be made and also an operation where the dotted line, as for one second, had been completed prior to the opening of the second circuit breaker but before the closing of the first circuit breaker. Also, there has been described an operation where one or more breakers may open and close--all in one second or such predetermined time as may be found desirable to have the shaft 43 revolve.

One type of operation is where the first circuit breaker may open causing the switch 20 to start the operation hereinbefore described and causing the time to be printed on the margin of the chart and causing stylus 3G to start making a dotted line as already set forth. After the first stylus lill, `for example, has been recording for 1A; of a second, another circuit breaker opening will likewise cause the stylus 33a to begin making a dotted line. If, after being in operation 1/2 second, the first circuit breaker whose operation is recorded by the stylus 30, should close, the operation of its switch 2li to dce-energize the relay coil 25a, will stop recording by the stylus 30.

This closing of the ilrst circuit breaker will not, however, stop recordingT of the second stylus 30a which will continue until the end of the second or such predetermined. time as the shaft 43 may be set to revolve in one cycle. In an operation such as has just been described, assuming a record sheet travel of 3 inches per second, there will be a line of dots 1.1/2 inches long in the path of the stylus 3Q with no dots during the last part of the travel. In the line of travel of the stylus 30a, there will be no dots during the first 1/4 of the sheet travel or 1% inch and a line of dots 11/4 inches long during the last part of the second 0f travel. From inspection of this record, it may be readily seen that both circuit breakers will have been open at the same period for 1A; second as indicated by the over-lapping o the dotted lines, which would be interpreted as follows: The date, hour, minutes and seconds that the breaker opened will be printed by the time stamp. The second breaker will have opened l/;t second later than the recorded time. The rst breaker will have closed 1/2 second after the recorded time. The second breaker will still be open one second after the recorded time and its closure later would be indicated in another cycle.

In the example just described, the first circuit breaker might have closed 1A; secondafter it opened while the second circuit breaker might have opened 1A second after the first circuit breaker opened. In such a case, the stylus 3D would have marked a line of dots for the first 3/1 inch, indicating 1A, second, and no line for the iinal inches or Q4; second. And while the movement was going on, the stylus 35a, would have been marked no line for the first 11/2, inches, or t@ second, and a dotted line for the last 11/2 inches, or 1/2 second.

In Fig. 2, which is an illustration of a record sheet, there is represented the record of the opening and closing of two circuit breakers, No. 1 breaker record being next to the dating column and the record of No. 2 breaker adjacent thereto. In this gure, dots are used for the illustration but for the sake of clearness of illustration, no attempt is made to illustrate the l2@ dots which would be made per second (three inches of record travel) during operation of the shaft 43 with a circuit breaker open.

In order to understand the recordings on the record sheet, the following analyses are made of the recordings for these breakers. It is to be understood that the record sheet it travels from top to bottom, as illustrated, the Styli remaining 15 in their respective positions. 40, Fig. 1 shows:

The record sheet In computing intervals of time with this invention, it is to be noted that for times over one second, there may be an error. This is due to the fact that the time clock is set to stamp times in intervals of one second, with the equipment described. Times for less than one second will be determined by the number of dots in the dotted lines made by the styli as already described.

The details of the time clock used, which are well known in the art, involves the advance of the clock type wheels, so as to indicate a second of change, as each second passes. It is thus obvious that the type wheel might type 11:40:21, indicating the time as forty minutes and 2l seconds past eleven; when the actual time might be 11:40:211-96. Thus the interval might have a 1%; second error. Thus the error is plus or minus one second for intervals over one second.

When, however, greater accuracy is desired, it is only necessary to change the drive gearing to have the shaft 43 move the record sheet, 2, 3 or n seconds during one cycle of record. In addition to this a clock may beemployed which will record times of shorter interval, thus further reducing possible error.

Conversely, if less accuracy is desired, the time clock may print time at greater intervals than one second and the record sheet speed can be adjusted to run through as much length as desired during the interval selected. It has been found in practice, however, that with record sheet speeds running at less than 3 inches per second, 60 cycle alternating current will not produce distinct dots and lengths of lines must be used for determining fractional parts of the interval.

It thus appears that the amount of detailed information printed by the time stamp-and its accuracy will be determined by the needs of the particular use to which the recording device is put.

In predetermining the speed of travel of the shaft 43 to advance the record sheet at the desired speed, the diameter of the roll over which the sheet is driven, the diameters of the gears connecting the constantly driven power motor with the one-revolution clutch 45 and the speed of the motor may all be varied to bring about the results sought.

From the foregoing description it is clear that l. the real purpose of the switch 20 is to cause energization and de-energization of the relay 25.

The red light 23 and the green light 24 are mere convenient indicating means to give information to the operative as to what is taking or has taken place. It is therefore clear that if the conduci tor 22a became broken or was omitted and the two lamps 23 and 24 were either removed or omitted, the operation of the circuits and devices connected thereto would still be as described. In other words, if a single-throw switch should replace the double-throw switch 20 and its connection was only to the point 29h to operate the relay coil 25a, with no indicating lights 23, 24, the functions of the several parts would :y still be retained.

It is to be also understood that the relay 3l and its coils, contact members and connections and the condenser 38d may be an integral part of the time stamp as marketed and the capacity of the condenser 38d would be determined by the manufacturer so as to properly function with the coacting parts of the device.

To one familiar with the art it will be clear that there can be many control circuits made which will cause the several items of equipment to,l properly perform their respective functicn s. While al1 of thosecannot be enumerated, it obvious to those skilled in the artthatthat partof the circuit throughV the armature, 35c contact 351, conductor 35h andcondenser 35g-,is notessential to the operation,` ,but is providedias a safeguard in case the relay coil: 38a fails to function properly. The conductor `381? couldbe connectedr directly to the conductor 21a and-the relay 35-with the connections 34h, 351e, 36,2311 and the contact member 31a eliminated.

It will be 'further clear to those skilled inthe art that if direct currentis not available, from service lines the direct current coils heretofore described may be energizedfrom a rectifier;of, suitable type which may be provided to give a, direct pulsating current for the-relays asA shown and described.

if desired, direct-current may be substituted for the alternating current, in which case, the record line onthe record sheet, instead of beine madeby dots would bel continuous and thelengthy of the line instead-of tbeinuniberfofgdots, would indicate the time.

One of the important featuresy of the inventiom it is now believedto be clear',l is the coordinated action betweeny the means for causing simultaneously (1;) the printing of the time by the timestamp, (2) the commencement of the shortl but continuousrecord at the beginning of the cycle, whichis accurate to 1/120,V of a second and (3),the starting of the-record so that the stylus,A by the number of alternating current dots or bythe length of a line made by direct current, may; indicate the length of time,A for exam,- plc, the circuit breaker opened and the lengthA of time itv was open if it was openy less than one second. This non-continuousguse of the record sheet advancing atghigh4 speed during long periods or" time when, for example, a'circuitnbreaker may belopen, results ina great savingY of' record sheet material.`
